Some of the biggest names in EDM will shake up international waters in 2015 on two Holy Ship! festival voyages featuring unique lineups. The first trip, which will travel round trip between Miami and Half Moon Cay in the Bahamas from January 3rd to the 6th, will feature sets by Knife Party, Pretty Lights, Flume, Boys Noize, A-Trak, Armand Van Helden and many more. The second adventure – which will float between Miami and Nassau and Coco Cay in the Bahamas between February 18th and 21st – will showcase sets by Skrillex, Fatboy Slim, Baauer, Baement Jaxx, Araabmuzik and many more.

As part of the trip, the first cruise will dock in Half Moon Cay, which hosts a pirate ship that the first Holy Ship! festival visited in 2012. It will also feature a day at sea with pool parties as it returns to the U.S. The second trip will spend more time with two different destinations in the Bahamas. In addition to the music sets, each trip will also feature onboard activities, theme nights and workshops with artists; the lineup for the latter has not yet been revealed.

The 2014 edition of Holy Ship!, which was held over four days in January, featured performances by Pharrell Williams, Diplo, Chromeo, Disclosure, Zedd and more. It also featured a surprise appearance by Dutch DJ Tiësto, who flew himself in. Afterward, he made a video, which Rolling Stone premiered, of him hanging out with his DJ friends and organizing a conga line around the ship’s decks. “I’m friends with a lot of DJs who’ve played Holy Ship! before and they told me how awesome an experience it is,” he told Rolling Stone. “I wanted to play in the past but couldn’t make it work with my schedule. This year, I flew down on my own and surprised everyone on board. It was a wild time as you can see from the video!”
